From 7bedebcaad351108a8f6eab6a031f2be2c06b613 Mon Sep 17 00:00:00 2001 From: =?utf8?q?SZEDER=20G=C3=A1bor?= Date: Fri, 27 Jun 2008 16:37:15 +0200 Subject: [PATCH] stash: introduce 'stash save --keep-index' option MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 'git stash save' saves local modifications to a new stash, and runs 'git reset --hard' to revert them to a clean index and work tree. When the '--keep-index' option is specified, after that 'git reset --hard' the previous contents of the index is restored and the work tree is updated to match the index. This option is useful if the user wants to commit only parts of his local modifications, but wants to test those parts before committing. Also add support for the completion of the new option, and add an example use case to the documentation.
